Xiaomi India — Service center not repairing

Address:

560017

I had bought a phone form flipkart of Xiaomi on January 2015 by Rs 9999, which stopped working on 22 July 2016 and I gave it to their service center on 22 July 2016 for repairing, but I have still not received the phone, every time I went to them they turned me down saying they do not have the spare parts to replace.
Initially they asked me 2 to 7 days, but still today they have not repaired it.

Please help me in this regard.
